Hi,
I am thinking about a new port config target, which could make setting
up MacPorts much easier. Currently, the appropriate variables for PATH,
MANPATH and DISPLAY are determined in the postflight script. If we would
move that into a port config target (or port setup, the name is open for
discussion), the manual setup process would become easier.
To get the env vars needed for your system, you would type:
port config --envvars
which would output:
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export MANPATH=/opt/local/share/man:$MANPATH
But to support multiple shells, this could be extended to also allow
port config --envvars --tcsh
which would output:
setenv PATH /opt/local/bin:/opt/local/sbin/:$PATH
setenv MANPATH /opt/local/share/man:$MANPATH
So the default should be auto-guessing which shell to use (current
$SHELL). There could be support for a lot of shells people are using.
The env vars which would be exported will be depending on the system
this runs on, e.g.:
Leopard: PATH and MANPATH
Tiger/Panther: PATH, MANPATH and DISPLAY
Another switch, port config --profile could output the profile file of
the current running shell. This would be .tcshrc for tcsh, .bash_profile
for bash, .zshrc for zsh and maybe others, too.
So after all setting up MacPorts could become just this line:
/opt/local/bin/port config --envvars >> \
$(/opt/local/bin/port config --profile)
Or a command /opt/local/port config --setup could do it all automatically.
The main purpose would be that we are moving this away from the dmg
installer and into base itself. So even if the installer postflight
script fails in future again, there would be an easy option to setup
MacPorts. Additionally this could also be useful for users installing
from source.
As the postflight script is broken in the 1.6.0 dmg, we have seen a lot
of people on IRC and the users mailing list looking for help how to get
MacPorts running. Telling them "set up your PATH manually" sounds too
complicated for some users and they might quit using MacPorts at all.
What do you think about such an option?
Rainer
